10 is attached, the said tube or sleeve opening through the partition into the oil chamber 6.

A tapering steam pipe 12 is engaged to the arm of the body 4 which is opposite the bonnet 10, and a fuel pipe 13 is arranged within, the steam pipe 12 and is engaged to the free end of the tube or sleeve 11. The

pipes 12 and 13 are concentrlc and both ta per outwardly or forwardly, the steam pipe 12 completely encompassing the fuel pipe 13. A needle valve 14 is screw-thre ded through the bonnet and passes ax ally forward within the fuel pipe 13 so that its steam or other heated fluid and is then atomized and sprayed by the steam in an effective manner.

The present invention further aims to rovide a burner of the character indicated so that the flame may be regulated and may be deflected out ofits normal path.

With the foregoing general objects out lined, and other objects in view which will be a parent as the invention is better under- .sto the present, invention resides in the novel construction and combination of arts hereinafter set forth and claimed, it

ing understood that this device is susggp; tible'of alterations or dexiations' itithiiifi't" 39 details within the scope of the appended claims without departing from the spirit of the invention.

The present invention has been illustrated.

in its preferred embodiment in th accom panying drawings, wherein 2- 4 Figure 1 is a longitudinal central section of the burner. Fig. 2 is an end view thereof. Fig. 3 isa sectional view taken on the line 3-3 of Fig. 1.

Referring specifically to the drawing, the burner embodies a cruciform body or casing 4 having a partition 5 therein form ing an oil chamber 6 and a steam chamber 7. A. steam pipe 8 is connected to one arm of the body 4 and communicates with the steam chamber 7 and an oil or liquid fuel pipe 9 is connected to the opposite arm of the body 4, which latter arm communicates with the oil chamber 6. A bonnet 10 is enarms of the body 4-, or that arm communicating with the 011 chamber 6 at right angles to the arm to which the pipe 9 is attached. To the partition 5 there is attached a short tube or sleeve 11, and whichlpasses throughthe arm of the bod t opposite the arm to which the bonnet tip is arranged adjacent the outer or forward end of the'pipe 1.3. The inner or rear end of the needle valve 14 protrudes beyond the bonnet 10 and bears a suitable hand Wheel 15, by means of which the needle valve may be rotated in order to adjust same lon gitudinally.

The outer or forward end of the steam pipe 12 is closed by a convex head it), and from the said head 16 projects a central nippic 17 and a pair of opposite and diverging nipples 18, the latter nipples and the former nipple being connected by ribs or webs 26. gflfheforward or outer end of the pipe 1: 'is part-ially closed by an inturned flange 19 against which the end 16 of the pipe 12 abuts, the said flange 19 providing a valve seat 20 against which the needle valve 14 is adapted to seat. The nipple 17 communi cates with the fuel pipe 13, and the nipples 18 communicate with the chamber between the two pipes 12 and 13, or the steam cham- ,ber 28.

A nozzle 21 is engaged to the nipple 17,

as designated by the numeral 27, and screwthreaded into the nipple 17. To the nipples 18 are attached the elbows 22, which have reduced portions 23 projecting from the ends of one of their arms and engaging in the said nipples, and the other arms 24 of the said elbows converge toward each other and are directed forwardly toward the tip of the nozzle 21. These arms 24 provide last nozzles for directing jets of steam toward the tip of the nozzle 21 and at a'point slightly inward from the tip of the nozzle 21, the jets being opposed in meeting the tip of the nozzle 21. Needle valves 25 are screw-threaded through the inner arms of the elbows 22 in alinement with the outer arms or nozzles 24, and are designed to consaid nozzle having its inner end reduced,

, ions and proportions, iliQ'S M. parts nemg readily assembled and take part.

using a burner. a pipe connect- .2; with a source of oil or th r 1d fuel, and the pipe 8 is connected with a source of steam or other heated tiuid, which will cause the liquid. fuel and steam to be fed to the oil chamber 6 and chamber 7, respectively, within the body l, from which, the fuel and steam will be admittedinto the fuel pipe 13 and the steam chamber 28, respectively. The steam is discharged from the chamber 28 through the elbows 22, the -convergingfete of steam issuing from the l'lOZZleS 24 meeting at the tip of the fuel nozzle 21-and tending to create a vacuum so to suck or draw the fuel forwardly. The dam within the chamber encompasses e uel pipe 13 and heats the said pipe and lel therein to such a degree as to ofely vaporize the fuel, the vapor thus 1d beingdrawn through the nozzle 21 a steamjets, so that thevapor will be ily m d with the steam, and so fuel will be eifectiv v atomized.

" u assumes "he shape, due ed. jets I which when .i g each other Spread fan like forms and carry therewith vapor. Ordinarily, the "ne'e a valves 25 are adjusted so that the streams or jets of steam have an equal we .city or pressure, thus directing the flames in a plane cutting the axis of the burner, and by adjusting one or the other or both, of the needle valves 25, the flames may be deflected upwardly or downwardly according to the varying pressures of the two jets of steam, as will be understood. The flow of vapor is readily regulated by adjusting the needle valve 14 to and from the seat 20, as will be clearly understood.

A fan like flame of advantage for the reason that the same covers considerable area, and not concentrated like a needle flame, which when. being directed toward an object tends to fuse the object. This burner when employed in a boiler will there fore not tend toburn the fines, grate bars or other parts, and at the same time will produce a high degree of combustion for providing 'a maximumheating effect with a minimum fuel supply. .This burner also of advantage for the reason that the flame may be deflected at various angles which may be found D-Ell beneficial and necessary, this being the burner, valves It has been found in practice that the 5,6 flame produced by the present burner, when burning oil, is white, thus indicating a thorough consumption of the fuel. It has also bcenfound that the fuel will not drip from the. fuel nozzle 21 and that the fuel is thoroughly grid effectively atomized and sprayed by the. steam jets, which in being brought-" in opposition provide for such results.

This burner is notonly useful for heating boilers, but may be employed for various purposes as will be understood by those skilled in the art.

Having thus described the invention what is claimed as new is 1. In a liquid fuel burner, a fuel nozzle, a needle valvefor. the fuel nozzle, a pair of opposite elbows, each having onearm diverging from the butt end of the said nozzle, the other arms of the elbows formingblast nozzles converging toward the tip of the said nozzle, and needle valves'adjustable in the former arms of the elbows in alinement with the latter arms.
